Immobilized microorganism sewage treatment drum

Abstract

The invention discloses an immobilized microorganism sewage treatment drum. The immobilized microorganism sewage treatment drum comprises a sewage treater, a magnetic field generator and a membrane component, wherein a water inlet is formed in the side of the sewage treater; an immobilized microorganism drum is arranged in the sewage treater; a filtering membrane is arranged on the periphery of the immobilized microorganism drum; water permeable bricks are arranged at the inner side of the immobilized microorganism drum and support the immobilized microorganism drum; the membrane component is arranged on the inner enclosure of the water permeable bricks; a water outlet is formed in the membrane component; the magnetic field generator comprises a spiral coil, a transformer, a power source, an iron cover and a magnetic field tester; the spiral coil is wound around the periphery of the sewage treater and is connected with the transformer; the transformer is connected with the power source; the iron cover covers the periphery and bottom of the spiral coil; the magnetic field tester is arranged in the sewage treater; aeration devices are arranged between the inner sides of the sewage treater and the filtering membrane. The immobilized microorganism sewage treatment drum combines immobilized microorganisms, aerobic and anaerobic alternative environments of the microorganisms and a magnetic field, thus enhancing organic matter degradation carried out by the microorganisms.

Description

technical field [0001] The invention relates to the field of industrial wastewater purification, in particular to an immobilized microbial sewage treatment cylinder. Background technique [0002] Industrial wastewater is usually treated biologically. However, temperature has an important impact on the growth, reproduction, metabolism, species distribution and population size of microorganisms, which in turn affects the efficiency of sewage treatment. In addition, temperature has a great influence on the activated sludge performance and the flocculation viscosity of wastewater. With the increasingly stringent sewage treatment standards, traditional industrial wastewater treatment methods cannot meet the requirements. Especially under low temperature conditions, the metabolic capacity of microorganisms is reduced, and the rate of chemical reactions is also reduced. Therefore, the efficiency of biological treatment of wastewater will also be reduced. [0003] The traditiona...

Problems solved by technology

[0003] The traditional activated sludge method is widely used in sewage treatment, mainly because activated sludge contains a large number of active microorganisms, which can quickly and effectively remove organic matter in sewage and have good nitrogen and phosphorus removal effects, but the traditional Activated sludge process sludge is mixed in a fluid state in sewage
